This application claims the benefit of priority from Korean Patent Application No. 10-2018-0170735 filed on Dec. 27, 2018, which application is herein incorporated by reference in its entirety.

BACKGROUND 1. Technical Field

The present disclosure relates to a vehicle lamp, and more particularly to a vehicle lamp capable of ensuring a high sense of unity when a plurality of lamp units are arranged based on a shape of an outer optical member.

2. Description of the Related Art

Generally, a vehicle is equipped with various types of vehicle lamps having an illumination function for confirming an object disposed in the vicinity of the vehicle at low light condition driving (e.g., at night), and a signaling function for notifying other vehicle or road users of the running state of the vehicle. For example, the main purpose of head lamps and fog lamps is the illumination function, and the main purpose of turn signal lamps, tail lamps, brake lamps, or side markers is the signaling function. In addition, the installation standards and specifications of such vehicle lamps are stipulated by regulations to allow each function to be fully utilized.

Among vehicle lamps, the head lamp forms various beam patterns such as a low beam pattern or a high beam pattern to secure a front view of a driver at low light condition driving, and it plays an important role for safe operations. The low beam pattern forms a predetermined cutoff line to prevent the occurrence of glare to a driver of a front vehicle such as a preceding vehicle or an opposite vehicle.

Recently, studies have been actively conducted to reduce the size of the vehicle lamp using a microlens having a relatively short focal length. When the low beam pattern is formed using a plurality of micro-optics provided on an optical member, the low beam pattern is formed by light emitted from the plurality of micro-optics, and a plurality of shields are provided to obstruct a part of light incident on each of the plurality of micro-optics to form a cutoff line.

As shown in FIG. 1, an outer lens 20 through which light is ultimately emitted may be formed in various shapes such as a curvature or the like based on a position where the lamp is mounted on the vehicle and the design of the vehicle. In this case, a plurality of lamp units 30 may be arranged in a stepwise manner based on a shape of the outer lens 20. However, the sense of unity is reduced and a lighting image may not be uniform due to the stepwise arrangement.

SUMMARY

The problems to be solved by the present disclosure are to provide a vehicle lamp in which the lamp is formed to incline at an incident surface of a first optical member and at an emitting surface of a second optical member. The problems of the present disclosure are not limited to the above-mentioned problems, and other problems not mentioned may be clearly understood by a person skilled in the art from the following description.

According to an aspect of the present invention, there is provided a vehicle lamp including a light source unit for generating light, a first optical member in which a plurality of incident optics are disposed on an incident surface on which light is incident from the light source unit, a second optical member in which a plurality of emitting optics are disposed on an emitting surface through which light emitted from the first optical member is incident and emitted, and a shield unit disposed between the plurality of incident optics and the plurality of emitting optics. In particular, a first side of the incident surface and the emitting surface may be formed to be closer to the light source unit than a second side of each of the incident surface and the emitting surface to allow the incident surface and the emitting surface to be inclined.

A vehicle lamp according to an exemplary embodiment of the present disclosure may have one or more of the following benefits. By forming optical axes of the plurality of incident optics and the plurality of emitting optics disposed on the inclined surface and the emitting surface in parallel with an optical axis of the light source, beam patterns may be more efficiently formed.

The benefits of the present disclosure are not limited to the above-mentioned benefits, and other benefits not mentioned may be clearly understood by a person skilled in the art from the claims.

FIG. 4 is a side view showing a vehicle lamp according to an exemplary embodiment of the present disclosure. FIGS. 5 and 6 are exploded views showing a vehicle lamp according to an exemplary embodiment of the present disclosure.

In an exemplary embodiment of the present disclosure, the vehicle lamp may be a head lamp that is used for the purpose of securing a front view by irradiating light in a driving direction of a vehicle when the vehicle drives at night or in a dark place such as a tunnel or the like. However, the vehicle lamp according to an exemplary embodiment of the present disclosure is not limited thereto, and it may be used not only as the head lamp but also as various lamps installed in a vehicle such as a tail lamp, a brake lamp, a fog lamp, a position lamp, a turn signal lamp, a daytime driving, a backup lamp, or the like.

Further, when the vehicle lamp is used as the head lamp in an exemplary embodiment of the present disclosure, the vehicle lamp will be exemplified for the case where it forms a low beam pattern that prevents light from being irradiated on an upper side based on a predetermined cutoff line to prevent the occurrence of glare to a driver of a front vehicle such as a preceding vehicle or an opposite vehicle. However, this is merely an example for facilitating understanding of the present disclosure. The vehicle lamp of the present disclosure is not limited thereto, and various beam patterns may be formed based on the usage, and two or more beam patterns may be formed simultaneously.

Referring to FIGS. 2 to 6, the vehicle lamp according to an exemplary embodiment of the present disclosure may include a light source unit 100, a first optical member 200, a second optical member 300, and a shield unit 400. The light source unit 100 may include a light source 110 and a light guide 120. As an example, the light source 110 may a semiconductor light emitting device such as an LED. However, the light source 110 is not limited thereto, and a semiconductor light emitting device and various other types of light sources such as a bulb may be used as the light source 110. Depending on the type of the light source 110, a reflector or the like for reflecting light generated from the light source 110 to the first optical member 200 may be additionally used.

The light guide 120 may guide an optical path of light generated at a predetermined light irradiation angle from the light source 110 in order to adjust the angle to be parallel to an optical axis Ax1 of the light source 110, and to guide the optical path to the first optical member 200. The optical axis Ax1 of the light source 110 may be understood as a line that passes perpendicularly to a center of a light emitting surface of the light source 110, and the optical axis of the light source unit 100 may be understood as an optical axis Ax1 of the light source 110.

The light guide 120 may reduce light loss by allowing light generated from the light source 110 to be incident on the first optical member 200 by a maximum amount. Further, the light guide 120 may serve to adjust the optical path to allow the light incident on the first optical member 200 to be parallel to the optical axis Ax1 of the light source 110, thereby allowing the light to be uniformly incident on the overall first optical member 200.

In an exemplary embodiment of the present disclosure, the light guide 120 may be a Fresnel lens having multiple annular lenses, and thus, it may be adjusted to allow the optical path of light generated from the light source 110 to be parallel to the optical axis Ax1 of the light source 110 while reducing the thickness. However, the light guide 120 is not limited thereto, and various types of lenses capable of adjusting the optical path of light generated from the light source 110 such as a collimator lens may be used. Although the exemplary embodiment of the present disclosure has been exemplified for the case where the light generated from the light source 110 is formed as parallel light by the light guide 120 and guided to the first optical member 200, the light guide 120 may be omitted depending on the type and number of the light source 110 or the like.

The first optical member 200 may be disposed in front of the light source unit 100 and may serve to emit the light incident from the light source unit 100 to the second optical member 300 disposed in front of the first optical member 200. In the first optical member 200, a plurality of incident optics 210 may be formed on an incident surface on which the light generated from the light source unit 100 is incident. The plurality of incident optics 210 may be disposed on the incident surface of a first light transmitting unit 220 of the first optical member 200.

Further, a first side of the incident surface of the first light transmitting unit 220 may be formed to be closer to the light source unit 100 than a second side to allow the incident surface of the first light transmitting unit 220 to be inclined. However, the present disclosure is not limited thereto, and the first light transmitting unit 220 may be parallel to the light source unit 100.

In an exemplary embodiment of the present disclosure, the plurality of incident optics 210 may be a microlens having a relatively short focal length to reduce the overall size of the vehicle lamp of the present disclosure. Herein, the description “the first optical member 200 is disposed in front of the light source 100” may mean that the direction in which light is irradiated from the vehicle lamp of the present disclosure is forward. Therefore, the actual direction referred to may vary depending on a position and/or direction in which the vehicle lamp of the present disclosure is installed.

The plurality of incident optics 210 may be made of a material through which light is transmitted and may be disposed on the incident surface of the first light transmitting unit 220 that faces the light source unit 100. The plurality of incident optics 210 may be formed integrally with the first light transmitting unit 220. Alternatively, the plurality of incident optics 210 may be formed separately from the first light transmitting unit 220 and disposed or coupled on a surface that faces the light source portion 100 in the first light transmitting unit 220.

In an exemplary embodiment of the present disclosure, each of the plurality of incident optics 210 may be a substantially semi-cylindrical lens that extends in a horizontal (e.g., left-and-right) direction. In the plurality of incident optics 210, at least one incident optic disposed in the horizontal direction may form a row in the horizontal direction, and the row in the horizontal direction may be disposed in a vertical (e.g., up-and-down) direction. When the incident surface is formed inclined as described above, the plurality of incident optics 210 may be disposed in a stepwise manner from the first side to the second side based on an inclined shape of the incident surface.

As a result, the plurality of incident optics 210 may be disposed to protrude in the direction of the light source toward one side. Accordingly, an optical axis Ax2 of the plurality of incident optics may be formed parallel to the optical axis Ax1 of the light source or the parallel light that is the light incident on the incident surface of the first light transmitting unit 220. The reason for this formation will be described later in detail.

An emitting surface of the first light transmitting unit 220 may also be formed to be inclined corresponding to the incident surface thereof In the second optical member 300, a plurality of emitting optics 310 may be formed on an emitting surface for emitting the light incident from the first optical member 200, and the plurality of emitting optics 310 may be disposed on an emitting surface of the second light transmitting unit 320 of the second optical member 300. Further, in order to correspond to the incident surface of the first light transmitting unit 220, the first side of the emitting surface of the second light transmitting unit 320 may be formed to be closer to the light source unit 100 than the second side to allow the emitting surface of the second light transmitting unit 220 to be inclined. However, the present disclosure is not limited thereto, and the second light transmitting unit 320 may be parallel to the light source unit 100.

The plurality of emitting optics 310 may be made of a material through which light is transmitted. As described above, in an example, the plurality of emitting optics 310 may be disposed on the emitting surface of the second light transmitting unit 320 from which light is emitted. The plurality of emitting optics 310 may be formed integrally with the second light transmitting unit 320, or alternatively, may be formed separately from the second light transmitting unit 320 and disposed or coupled on a surface where light is emitted in the second light transmitting unit 320.

In an exemplary embodiment of the present disclosure, the first light transmitting unit 220 and the second light transmitting unit 320 may be disposed to allow their facing surfaces to abut each other. However, the present disclosure is not limited thereto, and the first light transmitting unit 220 and the second light transmitting unit 320 may be spaced apart from each other by a predetermined distance to diffuse light.

In an exemplary embodiment of the present disclosure, each of the plurality of incident optics 210 may be the substantially semi-cylindrical lens that extends in the horizontal (e.g., left-and-right) direction. Therefore, in an example, the light emitted from one of the plurality of incident optics 210 may be incident on multiple emitting lenses of the plurality of emitting optics 310 disposed in an extending direction of the substantially semi-cylindrical lens. In an exemplary embodiment of the present disclosure, the light emitted from each of the plurality of incident optics 210 may be incident on at least two or more of the plurality of emitting optics 310.

In an exemplary embodiment of the present disclosure, the plurality of incident optics 210 and the plurality of emitting optics 310 may correspond one-to-one. However, the present disclosure is not limited thereto, and the plurality of incident optics 210 and the plurality of emitting optics 310 may correspond to each other in one-to-many, many-to-one, or many-to-many depending on their shapes. By allowing the light emitted from each of the plurality of incident optics 210 to be incident on at least two or more emitting optics of the plurality of emitting optics 310, the spread characteristic of a beam pattern formed by the vehicle lamp of the present disclosure as described above may be improved.

In particular, in the plurality of emitting optics 310, similar to the plurality of incident optics 210, at least one emitting optic 310 disposed in the horizontal direction forms a row in the horizontal direction, and the row in the horizontal direction may be arranged in the vertical (e.g., up-and-down) direction. When the emitting surface is formed to be inclined as described above, the plurality of emitting optics 310 may be disposed in a stepwise manner from the first side of the emitting surface of the second light transmitting unit 320 to the second side based on an inclined shape of the incident surface. As a result, the plurality of emitting optics 310 may be disposed to protrude toward a forward direction.

An optical axis Ax3 of the plurality of incident optics 310 may be formed parallel to the optical axis Ax1 of the light source or the parallel light that is the light incident on the incident surface of the second light transmitting unit 320. Accordingly, the optical axis Ax2 of the plurality of incident optics 210 and the optical axis Ax3 of the plurality of emitting optics 310 may be formed at a same position, to allow the plurality of incident optics 210 and the plurality of emitting optics 310 to correspond one-to-one. However, the present disclosure is not limited thereto, as described above.

By disposing the plurality of incident optics 210 and the plurality of emitting optics 310 in the stepwise manner to allow the optical axis Ax2 of the incident optics and the optical axis Ax3 of the emitting optics to be parallel to the optical axis Ax1 of the light source 110, the beam pattern may be formed more efficiently. For example, as shown in FIG. 7, when the incident optics 210 and the emitting optics 310 are disposed based on a shape of the emitting surface of the inclined first light transmission portion 220 and the incident surface of the inclined second light transmission portion 320, the optical axis Ax2 of the incident optics 210 and the optical axis Ax3 of the emitting optics 310 are formed to be inclined, and thus, the beam pattern is formed inefficiently.

The shield unit 400 may be disposed between the plurality of incident optics 210 and the plurality of emitting optics 310, and may obstruct a part of light incident on the plurality of emitting optics 310 to form a cutoff line CL of a low beam pattern Pin FIG. 8. In particular, the cutoff line CL of the low beam pattern P may include an inclined line CL1, an upper line CL2 that corresponds to a driving lane, and a lower line CL3 that corresponds to an opposite lane.

The shield portion 400 may include a plurality of shields 410 formed on either an emitting surface of the first light transmitting unit 220 or an incident surface of the second light transmitting unit 320. For example, the plurality of shields 410 may be formed in a film form and attached to one of the first light transmitting unit 220 and the second light transmitting unit 320. In addition, the shield part 400 including the plurality of shields 410 may be separately provided between the first light transmitting unit 220 and the second light transmitting unit 320.

Each of the plurality of shields 410 may obstruct a part of light incident on each of the plurality of emitting optics 310 to form a cutoff line of the beam pattern. Each upper end of the plurality of shields 410 may include an inclined edge 411 configured to form the inclined line CL1, a first edge 412 configured to form the upper line CL2, and a second edge 413 configured to form the lower line CL3 2, as shown in FIG. 8. In particular, positions of the first edge 412 and the second edge 413 and positions of the upper line CL2 and the lower line CL3 may be inverted. This is because when an aspheric lens is used as the plurality of emitting optics 310, light that is incident on and emitted from the plurality of emitting optics 310 may form an inverted image.

The plurality of shields 410 may be disposed to form a row in the horizontal direction similarly to the plurality of incident optics 210 and the plurality of emitting optics 310, in which the row in the horizontal direction may be arranged in the vertical direction.

Further, referring to FIGS. 9 and 10, each upper end of the plurality of shields 410 may be disposed at a focal point F or the vicinity of the focal point F of the plurality of emitting optics 310. Therefore, first light L1 incident on the first incident optic 210 a of the plurality of incident optics 210 may pass through the focal point F or the vicinity of the focal point F and may be emitted from the first emitting optic 310 a disposed on the optical axis Ax2 of the first incident optic 210 a of the plurality of emitting optics 310. In addition, second light L2 incident on the first incident optic 210 a may be emitted from at least one second emitting optic 310 b proximate to the first emitting optic 310 a. Accordingly, as shown in FIG. 11, as the first light L1 is irradiated to a central region P1 of the beam pattern P and the second light L2 is irradiated to a spread region P2 of the beam pattern P, the spread characteristic of the beam pattern P may be improved, as described above.

Conventionally, as shown in FIGS. 12 and 13, a shield 41 of related art is provided between a conventional incident optic 31 and a conventional emitting optic 32, which configuration prevents a path of the second light L2 of the present disclosure from forming. Specifically, the conventional shield 41 is formed in a shape that shields all of the upper, lower, left, and right sides except the portion for forming a cutoff line of a conventional beam pattern. Accordingly, the light incident on the conventional incidence optic 31 is emitted only by the conventional emitting optic 32 disposed on an optical axis of the conventional incidence optic 31 by the conventional shield 41, and is irradiated to a central region PP of the conventional beam pattern as shown in FIG. 14.

Unlike the related art, in the present disclosure, the plurality of shields 410 may be formed and arranged by the inclined edge 411, the first edge 412, and the second edge 413 to form a second optical path. Further, the present disclosure may improve the spread characteristic of the beam pattern P and form the beam pattern P more efficiently than in the related art.

Referring to FIG. 15, the vehicle lamp according to an exemplary embodiment of the present disclosure may further include an outer optical member 500, in which the light source unit 100, the first optical member 200, the second optical member 300, and the shield unit 400 may be formed into a lamp unit 600. The outer optical member 500 may be an optical member through which light formed in the light source unit 100 finally transmits, and may be provided in front of the lamp unit. Accordingly, the light emitted from the lamp unit 600 may pass through the outer optical member 500 to form the beam pattern P. The outer optical member 500 may be formed of a lens, a mirror, a prism, or the like, and may be formed in various shapes. For example, as shown in FIG. 15, the outer optical member 500 may be formed to have a curvature.

Further, at least one lamp unit 600 may be provided behind the outer optical member 500. Therefore, although the plurality of lamp units 600 are arranged in the rearward based on the curvature of the outer optical member 500, since the incident surface of the first light transmitting unit 220 and the emitting surface of the second light transmitting unit 320 are inclined as described above, the incident surface of first light transmitting unit 220 and the emitting surface of the second light transmitting unit 320 may be arranged with a high sense of unity and may form a uniform lighting image. The angle at which the incident surface of the first light transmitting unit 220 and the emitting surface of the second light transmitting unit 320 included in the plurality of lamp units are inclined may also be determined based on a shape of the outer optical member 500.

Further, although the upper side of the incident surface of the first light transmitting unit 220 and the upper side of the emitting surface of the second light transmitting unit 220 are shown to be closer to the light source unit 100 than the lower sides thereof in the drawings of the present disclosure, the present disclosure is not limited thereto, and the lower sides may be formed to be closer to the light source unit 100 than the upper sides to conform a shape of the outer optical member 500.

As another example, the outer optical member 500 may be formed in a substantially circular shape. In this case, the upper side of the incident surface of the first light transmitting unit 220 and the upper side of the emitting surface of the second light transmitting unit 320 included in some lamp units of the plurality of lamp units 600 may be formed to be closer to the light source portion 100 than the lower sides thereof. The lower side of the incident surface of the first light transmitting unit 220 and the lower side of the light emitting surface of the second light transmitting unit 320 included in the remaining lamp unit may be formed to be closer to the light source unit 100 than the upper sides thereof. Based on the shape of the outer optical member 500, some of the lamp units may be disposed behind the outer optical member 500, and then the remaining lamp units may be disposed.

An inclination of the incident surface of the first light transmitting unit 220 and the emitting surface of the second light transmitting unit 320 of each of the plurality of lamp units may also be different from each other based on the shape of the outer optical member 500. It is described that the incident surface of the first light transmitting unit 220 and the emitting surface of the second light transmitting unit 320 are inclined only vertically (e.g., upward and downward). However, the present disclosure is not limited thereto, and the incident surface of the first light transmitting unit 220 and the emitting surface of the second light transmitting unit 320 may also be inclined in the horizontal (e.g., left-and-right) direction or the like based on the shape of the outer optical member. As a result, the inclined direction and the inclination of the incident surface of the first light transmitting unit 220 and the emitting surface of the second light transmitting unit 320 included in each of the plurality of lamp units 600 may be determined differently from each other based on the shape of the outline optical member 500.

A skilled in the art may recognize that the present disclosure may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. Therefore, it is to be understood that the above-described exemplary embodiments are illustrative in all aspects and not restrictive.
